Title: Scroll compressor for natural gas
Inventor: IGNATIEV KIRILL M
IPC: F04B39/06
Filed: 2000-11-06
Abstract: A scroll type compressor (10) has both a high pressure lubricant sump (110) and a low pressure lubricant sump (52). Lubricant from the low pressure lubricant sump is supplied to the various bearings, thrust surfaces and other moving components of the compressor. It is then routed in such a way that it can absorb heat from the motor windings thus maintaining the operating temperature of the motor (38). Lubricant from the high pressure sump (110) is supplied to the moving compression chambers (98) defined by the scrolls at a point intermediate suction and discharge. The lubricant supplied from the high pressure sump (110) is first cooled and then used to cool the low pressure sump (52) prior to being supplied to the moving compression chambers (98, 66). The compressed gas is routed through two lubricant separators (18, 128) and a gas cooler (16) prior to being supplied for its intended use.
